create my own Altar of Life

I would like a little corner dedicated to all that is sacred, somewhere with “good vibrations” that will remind me every day of my values and goals, to better myself and the world. I spend more time at work than at home, so it would be good to set it up there, in a discreet sort of way, so it can be interpreted as new age decoration rather than obeying spiritual need, depending on the emotional maturity of the beholder!
